Abstract:
Provided is a manufacturing method for an organic electroluminescence display apparatus in which processing uniformity is kept during partial removal processing of an electrode layer or an organic compound layer. The organic electroluminescence display apparatus includes: a substrate; and a light-emitting device including an organic compound layer including an emission layer sandwiched between electrodes formed on the substrate, in which: two or more of the light-emitting devices are provided, and the light-emitting devices are stacked in a direction perpendicular to the substrate; at least one of the electrodes and the organic compound layers in the two or more light-emitting devices includes openings; and the openings are positioned so as not to overlap with one another in the direction perpendicular to the substrate.
